t entering the conduit leading to the generator.

A further object of the invention is to provide such an inhaling device with a readily renewable face piece, thus rendering the device sanitary and enabling it to be used successively by dihferent persons.

A further object of the invention is to provide an inhaling device of this character which will be simple in its construction, inexpensive to produce and which will not be easily disarranged so as to render it inoperative.

Other object-s of the invention will appear as the device is described in detail.

ln the accompanying drawings F ig. l is a ing my invention; Fig. 2 is a longitudinal sectional view of such a device; Fig. 3 is transverse section taken on the line 3 3 of Fig. 2; Fig. 4 is a side elevation of the valve supporting member; and Fiel 5 1s a side eievation, partly brolren away, of a paper face piece, showing the same folded.

in these drawings I have illustrated one embodiment of my invention and have shown li the same as comprising a casing or .hollow body portion l, one end of which is contracted. as shown at 2, to provide a nipple by means of/which the casing may be readily connected with or disconnected from a conduit 8 leading to the generator or other source of supply for medicinal fumes or the like. As here shown, the nipple 2 fits snugly within the end of ferrule 4 carried by the conduit and is held therein by frictional Contact. The outer portionof the casing l is substantially cylindrical in form, as shown at 5, and has its outer edge flared outwardly, as shown at 6, and turned upon itself to provide a bead 7.

Suitable means are provided for connecting this casing or body portion of the in- 1925. Serial No. 43,097.

haling device with the mouth or nose of the user and this is preferably accomplished by the use of a suitable face piece. This face piece may be of any suitable form which will permit the user to inhale the fumes passing through the body portion l of the device. In the present instance, I have shown the face piece in the form of a flexible shield 8 which substantially frusto-conical in shape and has its outer edge shaped to fit about the face and to enclose both the nose and the mouth of the user. lt is desirable that a face piece of this character should be readily renewable, for sanitary reasons, and l prefer that it should be made of paper or other inexpensive material so that it can be discarded after use. The truste-conical paper shield, as here shown, can be folded flat upon itself to facilitate storage and shipping and then expanded into conical form when it is desired to use the same.

Various means may be provided for attaching a shield or face piece of this character to the body portion of the inhaling device. As here shown, the small end of the shield or face piece is adapted to be inserted within the body portion of the inhaling device and by proper manipulation can be caused to accommodate itself substantially to the contour of that body portion. To secure the same in position a retaining device or sleeve 9 is inserted within that portion of the face piece which lies within the cylindrical body portion. yilhis retaining device is of an external diameter slight-ly less than the internal diameter of the cylindrical part of the body portion and when it is pressed into place it will clamp the face piece firmly to the casing or body portion l.

l have interposed between the conduit 3 and the face piece means for preventing the breath of the used from entering the conduit or generator, this means being of such a character that it will permit the free flow of the fumes from the conduitto the face piece. Preferably this is accomplished by arranging within the casing or body por-tion 1 a valve of such a character that it will open during the inhalation of the user and will close during the exhalation of the user- 1f:-

rIhe valve may be'of Yany/suitable character but I have here shown alplate l0 arranged y ing'device'or sleeve 9;y Loosely mounted on `lil the outer sideoi the pl'atelO is avalve meinber l2 preferably in the forni of a disk o'. suf@ licient diameter to cover the openings 11 in the plate l0. This disk or'v'alve member is' Y mounted upon a stud lvvhich is rigidly secured tothe plate yl() and is'provided with y Vthe nose and mouth of the user the suction.

ahead la spaced a short distance from the ,plate l() so thatthe disk v12 can have free movement on the -studtoward' and from the n apertured plate.

so g arranged that an inhalation vvill cause said face piece tosnugly engage the vfaceof y' .the user and will openl said valve, and an exhalationlvvill close said valveend ylift the Y edge of saidface piece to permit the escape of the exhaled breath;vk N v i whereof; 'Ij affix my. signature JOHN F; CLASS..
